What is parameter mapping

HI ,
Can some one explain me what is parameter mapping and in what scenarios we need to use it??.

Hi
Web Dynpro ParameterMapping API - IWDParameterMapping
The parameter mapping is an instance of the UI element event. Therefore, it is defined at UI element level. You describe the parameter mapping for a UI element event using the wdDoModifyView method (see also Event Parameter and Parameter Mapping).
Since the parameter mapping is defined at UI element event level, each UI element event has a corresponding mapping information. Therefore, each UI element that can trigger events returns the mappingOf<UIElementEventName> method. This method returns an instance of the IWDParameterMapping interface. A button UI element with the onAction event provides the mappingOfOnAction that returns the current parameter mapping for the button instance.

Problems with Parameter Mapping

Hi All,
I have problems with parameter-mapping. For me its a black box, sometimes it works sometimes not.
Lots of times my mappings doesnt work, and I dont know the reason.
For example: I want to map my Execution-CO to the Display-CO. For that I map the in the affected Action.
But it doesnt work, although I do have the same Context Structures, because its the same CO. The technical Name is also the same.
What could it be?
Thanks for answering me
Bye Steve

Hi Andre,
sorry for my late answer, but I'm writing my diploma thesis and wasnt at work since wednesday and so I dont have a access to our GP-System.
Hope I understood you right.
The Use Case of parameter mapping is that Users of further steps has the possibility to see the Input of previous steps.
When I dont map the parameter inside one action, it isnt possible. I tried it out with the SAP example "Time-off-process". I took the CO "Create Request" and add it in one Action (as Display & Execution). When I understand you right mapping inside an action is not necessary, to see the Inputs from further Actions --> But this way I cannot see the Inputs.
The mapping of my application works before I changed it.
I know never touch a running system, but It was necessary, we need a new Input and Output Parameter.
Cause I have 20 parameter the mapping was very time-consuming, to map every single parameter. I read a method to reduce the time: Adding a structure requires only mapping of the two structures. But now the Mapping doesnt work.
Hope you can help me

Parameter mapping for an action

can anybody help me with this parameter mapping.
how we can pass a parameter for an action.
and how to use that parameter in the implemented coding.

Hi sarbjeet,
Rajat has correctly explained your requirement.
Let me give you example.
say when the User opens your application it shows a page with one drop down which conatins some values and a button. So If you want to get the value selected by the user on click of the button, then you need to associate a action with the button(which you can define in action property of the button and it will automatically create the method and you can check it in the implementation tab). Now you can write the code for getting the value from drop down in this method. after getting the value you can do what ever logic you want to perform like inserting it into database etc.
Hope this will clearify logic. If you require the code then please let me know.
Regards
Narendra

Parameter mapping warnings

I am using sp12, and am wondering if something has changed with parameter mapping, because I am using the same method I used when I was on sp9, but am now getting compilation warnings about my parameter mapping.
I have an action with a string parameter. I bound the onAction property of several linkToAction elements to this action, and set up the mapping in the doModifyView method (retrieving each element by name, casting them to IWDLinkToAction objects, and calling addParameter to add the mapping). It builds and runs ok, but shows two warnings for each UI element I have mapped this way:
1) UIElementEventBinding onAction: Parameter <paramName>(string) cannot be supplied
2) LinkToAction <elementName> [onAction]: Action and event are not compatible
Any ideas on what I'm missing here?
Thanks,
-Dave

These warnings are meaningless, if you are unhappy with them, open an OSS message.

ACE - need help implementing basic parameter map

Hi,
I'm trying to implement a connection parameter on an ACE module that sumply sets the TCP timeout to 0.
I can get this to work fine if I permit all TCP traffic in the class-map, but it doesn't work if I use an ACL;
>>Match all TCP;
parameter-map type connection TCP-Timeout
set timeout inactivity 0
class-map match-all TCP-Timeout-Out-Class
2 match port tcp any
class-map match-all TCP-Timeout-in-Class
2 match port tcp any
policy-map multi-match TCP-Timeout-Out-Policy
class TCP-Timeout-Out-Class
connection advanced-options TCP-Timeout
policy-map multi-match TCP-Timeout-in-Policy
class TCP-Timeout-in-Class
connection advanced-options TCP-Timeout
Interface vlan 920

Interface vlan 323
service-policy input TCP-Timeout-Out-Policy
Any ideas?
Many Thanks

Try changing the class-map from "type match-all" to "type match-any". Match all implies both statments need to be true. The match-any is probably what you want. Either of the ACL statements can be true.
Also try to apply the policy globally instead of the interfaces, simplifying the config might help as well.
e.g.:
access-list TCP-Timeout-Group line 10 extended permit ip 10.221.178.0 0.0.0.255 any
access-list TCP-Timeout-Group line 20 extended permit ip any 10.221.178.0 0.0.0.255
class-map match-any TCP-Timeout-Class
match access-list TCP-Timeout-Group
parameter-map type connection TCP-Parameter-Map
set timeout inactivity 0
policy-map multi-match TCP-Timeout-Out-Policy
class TCP-Timeout-Out-Class
connection advanced-options TCP-Parameter-Map
service policy input TCP-Timeout-Out-Policy <- apply it globally
Hope it helps.

Input Parameter Mapping is not working in Sap HANA

Hi, We created on ANALYTICAL view(A) with Input Parameters, on top of Analytical view created one Calculation view(B) and mapped Calculation view input parameter with Analytical view input paramter and its working fine. Finally we created one more calculation view on top existing calculation view(B) and mapped with corresponding input parameters. Input parameter mapping is working fine in between A(analytical view) and --------> B (first Calc view) but input parameter mapping is not working properly in between B(first Calc View)-----------C(second Calc View). it is giving all data whatever is coming from Calc View B. Kindly help us to resolve this.

Hi,

Oracle App Server 10.1.3.1 + Struts2 parameter map loss

hi,
I am facing an issue with oracle app server 10.1.3.1. With an application deployed in it, any .action hit seems to lose the parameter map. However, i m using Spring MVC with jasper reports for reporting purpose. So hitting a .report seems to go thru without the parameter map loss. I m using struts 2.0.11 in the application.
I have also tried the workaround related to struts.properties - (struts.dispatcher.parametersWorkaround = true). Did not help.
I wrote a CustomActionMapper which is an exact copy of DefaultActionMapper but for the addition of a few log statements to see the parameter map and uri.
I can notice the paramter map coming out empty even when data is posted or queryString with parameters sent.
Any leads on this truly appreciated.

About parameter mapping

Hi experts
can anybode tell me where the variable is defined when i use parameter mapping? thanks a million!

Hi,
I think you want the details of these parameter mapping as documents.
Hope below link will help you:
[http://help.sap.com/saphelp_nw04/helpdata/en/8f/aa63688343bd40aafc537971aee068/frameset.htm]
If you see the UI elements details in this link you will find Event Parameter in Events section for each UI element.
And you can use these parameter mapping in wdModifyView().
thanks & regards,

What is M_ACTOR_N_ENDING mapping to the XI 3.1 schema?

Hi,
I don't know the M_ACTOR_N_ENDING mapping to the XI 3.1 schema.
Please can anybody tell me What is M_ACTOR_N_ENDING mapping to the XI 3.1 schema?
Thanks in advance
Amol Mali

BusinessObjects 6.5 schemas do not translate over to XI 3.1 schema.
Furthermore, unlike 6.5, the XI schemas are not for public use - most relevant non-indexed fields are Blob objects that you'd not be able to parse.

Ted Ueda

Same parameter-map used on 2 different classes

Greetings,
If the same parameter-map (type connection or http) is used on two different policy-map classes, will that create a conflict in how traffic for each of serverfarms uses persistence or inactivity timeout (script 1)?
Should we create a different instance of parameter-maps for each policy-map class (script 2)?
Script 1

What is Multi mapping

Hi All,
What is Multi Mapping ??
How many Types of Multi mappings r there ???
Please Explain a Little bit
Regards
Vamsi

Multi-Mapping can only be used in ccBPM. It is used to map abstract interfaces. Development is the same as Message Mappings
n:1 Transformation
Bundles multiple messages into one message, for example, individual purchase order items into one purchase order.
1:n Transformation
Splits a message into multiple messages, for example, a purchase order into the individual purchase order items.
n:m Transformation
Converts a message into another message, for example, a message that is defined by interface A is converted to message that is defined by interface B.
Multi-Mappings reference multiple message structures:-
a) All source message structures are combined into 1 source structure.
b) All target message structures are combined into 1 target structure.
Therefore, there is only one source structure mapped to one target.
Multi Mapping

Parameter Mapping with RFC Callable Object not working

Hi Folks
Scenario
I have a process scenario like this
Interactive Form Callable Object A -triggers> Process [Interactive Form Callble Object B -> Interactive Form Callble Object C -> RFC Callable Object ]
All the forms A, B, C use same form template, different sections of it lets say i, j and k are filled by different guys.
Now my parameter mappings are as follows -
a) Page level meeting between B & C called P Map.
b) Process parameter mapping with Form A and appropriate section of P Map lets say section i
c) fields of Form C are mapped to RFC callable object fields
Problem
The data filled in Form A [section i] disappears when I open and see the Form B.
If I remove the mappings of fields of Form C with RFC callable objec fields, I am able to see it.
Has anyone faced it before!

Hi,
This is a known issue on SP10 and it will be fixed in the next patch for SP10.
Hope this helps!

What is parameter id and default component in data element? Help!

Hi experts,
In the further characteristics, What is parameter id and default component name in data element? what are they used for?
Example: S_CARR_ID.
Thanks
Gopal

Hi,
Parameter ID :- Is used for assigning value to field.
Suppose u call a transaction in u porgram.
and u want to assign some value to field before executing the transaction.
if the field has parameter id u can assign value to field before calling the transaction.
that is it take the default value from the memmory.
and u set value in the memmory using parameter id.
----
GET PARAMETER -

Basic form 3
GET PARAMETER ID pid FIELD f.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See ABAP Unicode - Other Changes
Effect
First, the value stored under the key pid is transferred from the local SAP memory into the field f. If this key is not available in the local SAP memory, the value stored under the same key pid is transferred from the global user-related SAP memory to the field f.
A parameter ID can have up to 20 characters. You can find an overview of the keys (parameters) used in the SAP system description or the appropriate function in the ABAP Workbench.
The Return Code is set as follows:
SY-SUBRC = 0: A value was read from SAP memory. SY-SUBRC = 4: No value was found in SAP memory under the specified key.
Notes
The global user-related SAP memory is available to each user for the entire duration of a terminal session. For this reason, set values are retained when you leave a program.
You should not use SAP memory for temporary storage because a user's parallel sessions use the same global memory.
Example
Read the program name from SAP memory:
DATA : REPID LIKE SY-REPID.
GET PARAMETER ID 'RID' FIELD REPID.
----
SET PARAMETER -
SET PARAMETER ID pid FIELD f.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See ABAP Unicode - Other Changes
Effect
Writes the contents of the field f to the global user-specific SAP memory and the local transaction-specific SAP memory under the ID pid. Any existing values under the same ID are overwritten.
Parameter IDs can be up to 20 characters long. They cannot consist entirely of spaces. The SAP system description contains an overview of parameter IDs. You can also produce a list using the ABAP Workbench.
Notes
The global, user-specific SAP memory is available to a user for the duration of a single terminal session. Values written to it are retained even when the user exits a program.
Do not use SAP memory as a temporary storage area, since parallel sessions belonging to the same user all use the same memory area.
Only store data of the types C, N, D, and T, as well as structures that consist of these types, in the SAP Memory.
You can create new parameter IDs using the ABAP Workbench.
Parameter IDs may have a namespace prefix.
Example
DATA REPID like sy-repid VALUE 'RSPFPAR'.
SET PARAMETER ID 'RID' FIELD REPID.

What is XSLT mapping ? where it can be carrid out in PI?

Hi all,
What is XSLT mapping ?
Where it can be carrid out in PI?
How it is useful in excel to RFC scenario ?
Can some one help on this please?
Regards
Venkat

Hi
XSLT is one type of mapping that Xi supports. XSLT mapping also do have certain advantages like if you need a formatted output like HTML in XSLT it would be easy to implement... XSLT is a W3C standard so if also works in any other integration s/w other than XI so it is portable.
Advantage
the changes to XSD's loses all mappings with graphical mappings but with XSLT's you just add the field changed or added, instead of starting over
